Shock Box

Introduction: Shock Box

this is a little toy that delivers a mild shock at the touch of a buttonif used as directed this project will give a non-lethal shock that's kind of fun

this project will never need to be plugged into mains voltagei am never responsible for anything you doi actually stumbled across this concept via painful accidenti applied power to a transformer then when i turned the power off it shocked mei tried it ten more times and figured out what what was happeningpower was being transformed and then stored in the inductance of the transformer then being released as a shock(somebody correct me if i'm wrong or they find something smarter)(knowledge is power)

Step 1: Matreials and Tools

materials:-9V battery snap-or--alligator clips-ac/dc transformer-clickey switch-2ft light grade wirethe transformer needs to be at least 5V and 300ma. just nothing wimpy.a 9V battery is preferred but you shouldn't use anything stronger or you could hurt yourself.you can use the battery clip or the alligator clips, either is fine.

Step 2: Open the Transformer

i used a grinder to go around the edge of the the transformerthe grinder will shoot hot molten plastic at you so use safety glassesyou can use a screwdriver or a knife but it will take longertry not to completely destroy the case or the insidescut the transformer away from the circuits and try to keep the wires long

discard the circuitry or keep it but you wont need it for this projectkeep the case to put the transformer back intopull out the ac power prongs and save them for later use

Step 3: Cutting the Transformer

find the ground wires on the secondary coil and cut the rest off

if your transformer has three wires(most do) use the first and second wire but cut the third off(the third and first are interchangeable but only use one of them not both)

be sure you're working on the secondary coilcut off the primary coil wires because you don't need themthe secondary(output) coil has fewer wraps thicker wirethe primary(input) coil has more wraps of thinner wire

Step 4: Wiring

cut a the following lengths of wiredouble strand:-8 in-6in-2insingle strand:-2in

strip all the wires 3/4 of an inch on all ends

connect all the wires according to the diagramyou can solder the connections but it's not necessary

Step 5: Conection

connect the two leftover wires to the transformer leadsapply electrical tape to all of the stripped endscut a hole in the case and slip the wires and the switch through the hole

i melted the switch to the case with my soldiering iron but you can attach it however you like

Step 6: Closing and Usage

melt the back of the case to the front piece with a soldiering ironor... you could just wrap the entire thing in duct tape

usage

connect the battery to the clipsit doesn't matter if its backwards because were working with non-polar electricityi completely made that up but it doesn't matter +/-

take the shock terminals in your pointer middle and thumb fingersbut make sure they don't short out or you wont get any shock

press the switch for half a second and when you let go it will shock your fingers

the harder you squeeze your fingers the more shock you getyou can press the switch rapidly on and off to get a rapid and slightly painful shockyou can also try a trick with your friendsmake a circle of friends as many as you can getthe first friend and the last in the circle each grab one shock terminaland you click the buttonall of your friends will scream and you'll just laugh at themlol lol lol

It seems apparent that you don't respond to your comments or questions, but I will pose mine instead. Why do you use the transformer at all? what is its purpose in your design? you don't use its induciton ability due to the DC input and you disregaurd the primary inputs. it seems to me that you just use it as a capicitor of a sort.

That is a great instructable! I had built is shocker as soon after I read your instructable, and went outside and started shocking all of my friends and they all had scream after they got shocked by my shocker! Lol!! What a great toy!
Thank you for that great instructable!

i once used 3 9V batteries. holy something. i got this kids funny bone and his arm completely started spazing. this is not really recommended. and its not really recommended to use is at school. teachers are scared of lightening or anything that hurts

I used a 9v battery on a alarm clock transformer, it did not hurt that much, but I tried using a bigger transformer, it hurts even more! (Ouch!!) So I think the size of the transformer does matter, the bigger the transformer you use, the more painful the shock will be... And also I NEVER used the shocker at the school because I think the shocker is considered as a weapon, (like a stun gun) so I don't take it to the school because I don't want to get in trouble.

hey plamana, besides the ones you posted up, do you know any other ways to make a shocker? like... on a solderless breadboard? so its a little easier for people who cant really solder as good as you. people like me
